NATCHEZ — Buildings that once housed International Paper’s Natchez administration will be demolished.

The Adams County Board of Supervisors has approved the demolition of the former administration building and an adjacent library at the former IP site, which is now owned by the county.

“We are looking to remove some of those buildings that are no longer in use and have no use actually,” Adams County Board of Supervisors President Darryl Grennell said. “They have significant leaks and other issues that are beyond repair.”

John Tidmore/TDT Contracting will demolish the buildings at no cost to the county, Grennell said.

“This company, they are going to come in and crush the material, the bricks and concrete, and they will use it to make a substrate that kind of acts like gravel that they use,” he said.

The company will also give the county 10 tons of the mixed substrate, Grennell said.

Board Vice President Mike Lazarus said the contractor will not be scrapping the metal materials at the site.

The county will put out separate proposals for scrapping the metal, he said.

Grennell said the county government sent its maintenance department and IT director to see if anything from the building could be salvaged before it was demolished.

“We had already been through and gotten the bulk of what was useful,” he said. “They just went back through to make sure there was anything of use in there.”

Some of the property’s larger structures will remain for the time being.

Adams County bought the former IP property in mid-2013 from Rentech, which had purchased the shuttered industrial site in 2008 with plans to construct a coal-to-liquid fuel plant.

Rentech’s plans never materialized, and when the company put the property up for sale the county bought it at the behest of Natchez Inc. so the county could better control its marketing and rehabilitate an industrial water treatment plant on the 478-acre site as a broader economic development tool.

International Paper closed the plant in 2003.
